I want to say real quick that the DGF hadn't left a cigarette in the shed. He had been using a propane torch & the fire inspector said that the fire started in a bin of rags. The speculation is that a spark got in the bin. He has been known to smoke in there & that was what the family thought had happened.
I took care of the li'le girl yesterday while the parents dug through the house & found what was salvageable. There was very little but what they found was important.
